Divided and this application filed March 19, 1908.

Serial No. 421,984.

To all whom it may concern:

Be it known that I, ISAAC S. SHERWIN, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented new and useful Improvements in lVindow-Shade Holders, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The invention relates to devices for adjustably sup orting both the window shade and the sha e roller at different elevations on the window frame so that the roller and shade may be adjusted at any desired height as to the window and the admission of light maly thus be perfectly controlled.

he present construction is an improvement upon the construction shown in my Letters Patent N 0. 778,079 bearing date Dec. 20th, 1904; the matter hereinafter claimed is shown and described in my applicagion, Serial Number 376,611, filed May 31, 19 7.-

The objectof this improvement is to provide means for simplifying my former construction and adding thereto certain novel features which will be fully described in this specification and pointed out in the claims.

In the drawings, Figure 1 is a front elevation of a window frame provided with my improved window shade holder su porting a shade and roller mid-way of tlie frame. Fig. 2 is an enlarged side elevation of the same showing the improved arrangement of the cord and sliding fixtures, the central portion being broken away. Figs. 3 and 4 are perspective views of the sliding fixtures for supporting the respective ends of the shade r0 er on the side rods. Fig. 5 is a perspective view of the pulley bracket supporting the upper ends of the side rods. Fig. 6 is a perspective view of the sliding fixture and s ur in the end of the shade roller showing t e means of locking said spur in the fixture. Fig. 7 is a perspective view of the cleat or button'for holding the lower end of the cord on the window casing. Fig. 8 is a detail of the separating pin for the cord.

Sinnlar numerals refer to corresponding parts in the several views.

The numeral 10 indicates the window frame on which shade-roller-su porting rods 11 are vertically attached at eac 1 side in suitable brackets 12 at the top and 13 at the botsuitable apertures in brackets 12 and 13 and is provided with a head 20 at the upper end and a thread and adjusting nut 21 at the lower end beneath lower bracket 13 so that the nut may be screwed tightly against the bracket 13, thereby holding the rod taut as it draws on upper bracket 12.

The brackets 12 are prr-iferably struck out of sheet metal with an angular base through which suitable screws are inserted to hold the bracket on the casing 10. A pulley 14- is mounted in the opening 15 in the outer end formed by striking up the llange 16 therefrom to hold the side of the roller toward the casing, and bending the end in a parallel flange 17 on the outer end of bracket 12. The lower edge of outer flange 17 is turned outwardly in a projection 18, the projection being strengthened by means of connecting support 19 which forms with projection 18 a hooded recess for the head 20 of rod 11, the rod extending down through a hole in projection 18. A second hole is provided in the side flange 17 in the rear side of said hood and adjacent to head 20 through which a cord separating pin 22 is removably inserted, the rod 11 being inserted through the turned end 23 of pin 22 and when drawn down by the nut 21 on the lower and below bracket 13, the pin 22 is to the right and left sides and turning the attaching flange inwardly on each bracket.

The window shade 24 is supported on spring roller 25 on fixtures 26 and 27, whichfixtures are formed as shown in Figs. 3 and 1,

and are slidably mounted on rods 11 by means of the tubular ends 28 on the upper and lower sides of said fixtures. The arrangcment of the tubular ends 28 allows the fixtures to slide easily upon rods 11. Fixture 27 is made with a rectangular opening 29 to receive the squared spur 30 in the end of the spring roller 25; said spur 30 being inserted through hole 29 and a locking ring tom. The metal rod 11 is inserted through 55 The left upper bracket 12 is 90 in the opposite end of shade roller 25 from Y 1 r, that in wnrch the spur s0 is inserted. Tn

head of screw 0-) is inserted throng i a recessed opening 3 1 in the side of slot aria is locked in slot in the follow Flanges 35 are turned on the up 5 under edges of fix ture and holes (e provided in said flanges through which the operating cord 40 slidahly works. apparent that when the cord ll) inser through openings it vrill d across mouth of the recess 14 thr head or" screw 33 is adn itted to slot 11K cord 37 will close said recess so that L/l SSislochedwithhr slot 32. ltis appai i the corc may easily be raised when loosened and screw inay hen ac itted to recess 34 and removed from the fixture. Fixture 27 also has snnilar flanges 35 with holes 36 through which the end of the cord is inserted, the cord heing lniotted below fixture 27 as shown in Fig. 1. l he elevating cord is divided into t'av parts, a single strand or pull cord 39 and a double portion 37. My improved button or looking cleat 12 for the cord is pressed out of sheet metal with rounded ends 43 adjacent to the casing so as to easily compress the cord upon the cas' 1g. It is "found that when drawn taut one turn about this form of a cleat holds the cord secure. it is also found that it? screws are necessary to hold cleat 4L2 firmly in position so that the cleat cannot turn or give when the cord is pinched hetiveen'the cleat and the casing. The upper portion 37 of the elevating cord is attached to the single strand 39 by means of a loop in the upper end of strand 39 and the doubled end of the part 37. 3. is doubled in order to provide the two strands 40 and ll which are arrang" I as lOllOWSI Strand l0 passes through openings 86 in fixture 26 as above described and over pulley in bracket 12 and then returns to bracket 26 attaching through hole 38 and ending in a knot on the under side of flange 35. The other strand 41 of part 37 oi the elevating cord extends directly over pulley 14 alongside of strand 410 anc across the Window casing to the opposite bracket 12 and roller i l and to the opposite fixture 27 on the opposite end of spring roller 25 from fixture 26, passing through flanges 35 and ending in a knot belovr the fixture as above described. It is new apparent that both the fixtures 2'6 and 2. may be raised or lowered by means 01' the pull cord. The Weight of the Window shade and spring roller is SUfilClBIl'G to cause the same to drop down to any desired elevation when the cord is released and in order to elevate the shade,

it is only necessary to pulldo'wnivard' upon the cord 8%), thereby the two fixtures and 53'? with an exactly equal drew, from the double cord.

It is found that double strands 10 and 41 are apt to twist around one another as they work hack and forth particularly ivhe the Window shade is dropped to the lower portion of the Window and there is con- Lderahle length of the cords adjacent to one o Accordingly the separating pin 2 .od just beneath roller 1 1 as above and strand 10 is placed unon one i strand 4:1 on the other side oi said o l ag the two in their ondition and allowing t 0 two cords "-eely over t e roller and separate on cp osite side or the roller. Without seer-rating pin 22 the cord 41. was oite down toward fixture 26 by cord 10 sen a and the draw of the two cords was uneven noon the opposite end of the Window shade and consequently the WlllClOW shade was drawn out oi line with one end higher than the other. it is therefore obvious that pin 22 performs an exceedingly important ofiice in separating the cords so that they may always draw evenly on the fixtures 26 and 27.

it will be seen that the form of the brackets and fixtures is such that they can all he struck from the sheet steel by means of suitable dies and their cost thus reduced to the minimum .vhile their durability and strength are greatly increased.

I claim new:

A Window shade holder consisting of vertical guide rods each side of the Window and means for holding the same, fixtures slidahly mounted on said rods, a Window shade roller attached to said fixtures, one of said slidahle fixtures having a closed slot with a recess for the admission of the spur of said shade roller, flanges on the upper and lower sides of said slotted fixture having openings therein opposite the mouth of said recess, pull cord operatively engaging said openings and closing said recess mouth, and the opposite end of said shade rol or having locking enga ement with the other of said slida ole fixtures.
